 # Fuck Facebook
 
 A collection of tools to help you use Facebook when you don't want to
+
+## Usage
+
+Run `fuck-facebook --help` to get a list of options and explanations.
+
+To get all unread messages (that haven't already been reported) run these commands:
+
+```
+fuck-facebook --login
+```
+
+You only need to login once
+
+```
+fuck-facebook --unread-messages
+```
+
+This will only show you unread messages that have been received since the last time you checked.
+This way if you have emails going out for new messages, you won't get notified for the same message each time.
+
+## Config
+
+Here's a complete config file along with an explanation of each option:
+
+```yaml
+smtp:
+  from_email: [e-mail]
+  to_email: [e-mail]
+  address: smtp.example.com
+  port: 587
+  user_name: some_user_name
+  password: 123456
+  authentication: plain
+```
+
+These options can be passed as environment variables, by:
+* Joining the keys with `_`
+* Capitalizing the entire string
+* Prefixing the key with `FF_`
+
+For example the `smtp` `from_email` will become `FF_SMTP_FROM_EMAIL`
+
+Environment variables take precedent over the config file.
